     Find a value of a workspace variable and write it to a file.

     ## S4 method for signature 'netWorkSpace':
     nwsFindFile(.Object, xName, fObj)

_A_r_g_u_m_e_n_t_s:

 .Object: a netWorkSpace object.

   xName: character string specifying the name of the variable to find.

    fObj: 'file' object or character string specifying the file to
          write data to.

_D_e_t_a_i_l_s:

     The 'nwsFindFile' method looks in the shared netWorkSpace
     '.Object' for a value bound to 'xName'; if it finds such a value,
     'nwsFind' writes it to the specified file but does not remove it
     from the variable.  If no value is found, 'nwsFindFile' blocks
     until a value for 'xName' becomes available. If there is more than
     one value associated with 'xName', the particular value returned
     depends on 'xName''s behavior. See 'nwsDeclare' for details.
